3.11|11.1.1 安装新的客户端
在备份服务器上添加hosts信息
IP地址 客户端
{NBU Master IP地址} {NBU Master主机名}
解压NBU客户端安装包并运行安装程序,安装客户端
3.21|21.1.2 新建异机恢复文件
在备份服务器上建立支持异机恢复要求的文件。
备份服务器建立No.Restrictions空文件
Windows platform: InstallPath\netbackup\db\altnames\No.Restrictions
UNIX platform: /usr/openv/netbackup/db/altnames/No.Restrictions
3.31|31.1.3 新建数据库实例
对于需要恢复的机器,需要新建立一个数据库实例进行数据恢复。
本次恢复针到的实例为test
3.41|41.1.4 建立spfile文件
原spfile导出文件为:

由于需要恢复到单机,删除RAC相关信息。 另外由于硬件资源的不同,删除需要恢复的资源配置。
新的配置文件为
